Midea floor air conditioner shows what E14 means

The preliminary judgment is that the compressor phase sequence is reversed fault, and it is recommended to contact the manufacturer for processing.

If you still have questions, you are welcome to ask questions to the company in the United States; I wish you a smooth work and a happy life!

Midea's air conditioner shows that E1 is faulty**, which refers to an open circuit or a short circuit in the indoor temperature sensor.

The reason for this failure may be that the sensor is in poor contact or disconnected, please check whether the temperature probe on the air outlet is installed correctly or whether it is damaged, it is recommended that you find a professional maintenance worker to repair it!

Extended Material: Air Conditioning

Air conditioner is a room conditioner, which regulates temperature and humidity, and is a kind of air conditioner used to provide a space area (generally closed) to deal with changes in air temperature. Its function is to adjust the parameters such as temperature, humidity, cleanliness and air flow rate of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process.

Air conditioners are divided into single cooling air conditioners and cold and warm air conditioners, the working principle is the same, and the refrigerant generally used in air conditioners is freon. The characteristic of the fluoroli ion is that when it changes from gaseous to liquid state, it releases a large amount of heat.

When chaotic changes from liquid to gaseous, it absorbs a lot of heat. Air conditioners are designed based on this principle.

The compressor compresses the gaseous refrigerant into a gaseous refrigerant with high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows hot air.

Then to the capillary, into the evaporator (indoor unit), because the refrigerant from the capillary to the evaporator after the space suddenly increases, the pressure decreases, the liquid refrigerant will vaporize, into a gaseous low-temperature refrigerant, thereby absorbing a lot of heat, the evaporator will become cold, the fan of the indoor unit will blow the indoor air from the evaporator, so the indoor unit blows out of the cold air; When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water.

There is a component called the four-way valve during heating, so that the flow direction of the refrigerant in the condenser and evaporator is opposite to that of refrigeration, so when heating, the outdoor air blows cold air, and the indoor unit blows hot air.

In fact, it is the principle of expelling heat during liquefaction (changing from a gas to a liquid state) and absorbing heat during vaporization (from a liquid to a gas) that I learned in junior high school physics.

Midea air conditioner display E1 usually indicatesIndoor and outdoor communication failureIt is caused by the damage of the communication line between the indoor and outdoor machines, the failure of the communication board between the indoor and outdoor machines, and the communication signal interference between the indoor and outdoor machines.

How to deal with E1 failures:

First of all, you can unplug the air conditioner plug and turn off the power for 10 minutes, then plug it back in and power it on for observation. If the fault is still not eliminated:

1) Check whether the communication line is damaged or loose. If you find a problem, you can try reconnecting or replacing the communication line.

2) Check whether the communication board between indoor and outdoor units is damaged. If the communication board fails, you need to contact a professional air conditioner maintenance personnel for inspection and repair.

Midea's air conditioner shows "E1" which means: indoor and outdoor communication failure.

The failure of indoor and outdoor communication of air conditioners will lead to inconsistencies between indoor and outdoor phenomena, such as indoor power, outdoor power, or outdoor power, indoor unit power, and other fault phenomena.

Midea's air conditioner**E1 indicates the communication failure between the indoor unit and the outdoor unit.

Midea's air conditioner shows that the air conditioner is faulty**E1 may be a communication fault between the indoor unit and the outdoor unit. When E1 occurs, first check whether the connection cable of the VTH is broken, if the connection of the VTH is normal, the circuit board may be damaged. Examine.

Sensor body cable set is broken or broken, and if so, replaced. First of all, determine whether the air conditioner has failed after running for a period of time or fails when it is turned on, so as to distinguish whether it is a system failure or a circuit failure.

Air Conditioner Shows Air Conditioner Failure **E1 Description Compressor.

If the current is too large, the compressor is overheated, the exhaust temperature is high, and the module is protected, check whether the overload protector is disconnected and whether the compressor temperature sensor package is short-circuited. At this time, open the indoor case and observe the green color on the circuit board of the indoor unit.

The indicator light is shining, if it is shining, the outer board is bad, and if it is not flashing, the inner board is bad. This is because the green light will only turn on when the indoor unit receives the pulse signal sent by the external unit, and at the same time send a signal to the indoor unit, and the indoor and outdoor units communicate.

1. Midea's fixed-speed hang-up display E4 means: four times current protection.

Second, the maintenance and investigation methods:

1. Extract the compressor line group from the current transformer, if the air conditioner still has an overcurrent protection fault, it is a fault of the air conditioner circuit board;

2. Check whether the resistance value between the three terminals of the compressor is normal, for single-phase compressor, if the sum of the two resistance values is not equal to the third resistance value, it is judged to be a compressor failure; For three-phase compressors, if the resistance value between the three phases is unbalanced, it means that the compressor is faulty.

Midea's air conditioner hangs up and shows e丨 knows.

Hello:1 The indoor ambient temperature sensor is broken2 The indoor and outdoor communication is faulty.

Check the internal and external cables.

You can call ** to Midea air conditioning after-sales service customer service and ask what fault E1** means. Ask them to send someone to the door to check.

e14 fault phenomenon, or the display LCD panel does not display.

1. If it is a new installation, it shows that the E14 is basically the wrong phase sequence line. Adjust it and you're good to go.

2. If the old machine, which was used to be good, suddenly appears E14, it may be caused by the bad starting capacitor, the poor exhaust of the external machine, or the failure of the compressor itself, or the unstable voltage. Let's find a professional master to check it out.

During installation, the connecting cable will loosen or tear off the indoor fan hall feedback wire or display panel connection cable from the computer board after winding, which will lead to failure.

If there is a fault, it is still necessary to ask a professional to repair it.

E1 T1 sensor failure.

E2 T2 sensor failure.

E3 T3 sensor failure.

E4 T4 sensor failure.

E5 Indoor and outdoor communication failure.

E10 compressor low pressure failure.

E13 Compressor Phase Failure Failure.

E14 Compressor Reverse Phase Sequence Fault.

Adjust any 2 wires of the power cord.

This is a fault**, the air conditioner reports a fault prompt "e1", which generally means that the outdoor unit is not running, and it may be that the compressor of the outdoor unit is broken.

The fault of the Midea air conditioner display E1 may be the communication failure between the indoor unit and the outdoor unit, when E1 appears, first check whether the connection line of the indoor unit is broken, if the indoor unit is connected normally, it may be that the circuit board is damaged.

How many patterns are there? Refrigerant is missing. The condenser and evaporator are clogged with dirt. Clogged pipes.
